PRINTING-INK AND PROCESS OF MAKING SAME.

No Drawing.

To all whom it may concern:

Be it known that I, FRANK J. BAUMGARD- NER, a citizen of the United States, residing at Cleveland in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Printing- Inks and Processes of Making Same, of which the following is a specification.

My invention relates to an improved printing ink and process of making same, the primary object being to provide what may be termed a non-skin formin or nonevaporating printin ink adapte by reason of its improve composition and the proc ss of making same to meet the varying emands of actual service.

By reason of the above the usual skin or covering which forms or collects on printing inks within a very short time after exposure to the atmosphere is prevented, and, as is well known, this skin or covering is a constant source of annoyance, waste and expense. By reason of the prevention of the formation of this skin or covering it is believed that the present form of ink will save the consumer from 10 to due to this loss alone.

In attaining the above mentioned objects and carrying out the imfiroved process I use the ingredients hereina er referred to, entirely eliminating the use of artificial driers, such for example,--as the various commonly employed liquid driers, lead driers, manganese, linoleate, and the like. Furthermore, I use no linseed oil, resins, or varnishes.

In order to prevent the volatlhzation and evaporation 0 various valuable and necessary ingredients having certain desired properties and which would naturally result b the application of heat in the prohe ingredients are dissolved and compounded in what may be termed a cold process, as hereinafter referred to, and by reason of the improved process and the product resulting therefrom, the life of the composition rollers commonly employed on printing presses is preserved or extended as the mineral oil and ingredients used in this process are neutral to the glycerin and other substances of the composition rollers. In carrying out the improved method or rocess of making the improved printing ink I take approximately .47 mineral oil,

Specification of Letters Patent.

Patented Mar. 19, 1918.

Application filed January 25, 1917. Serial No. 144,382.

.53 of asphaltum, preferably what is commonly known as Assyrian asphaltum, adding thereto the desired coloring matter as required,such for example,as an oil anilin, a pigment base ground in mineral oil, or a carbon black ground in mineral oil, and dissolving by a thorough agitation and commingling by a cold process,or in other words,without the application of heat.

As is Well known to those skilled in the art to which this invention relates, it is now necessary to use printing inks of varying character to meet the varyin demands of the different stocks of paper, or example,- on a bond stock a heavy ink is required, on a coated stock, a soft ink, etc., and on various other stocks differently bodied inks must necessarily be used, and, furthermore, inks with difierent or varying bodies must be used in accordance with the difierent seasons of the year, while with my improved ink the same is of a character for universal application and is not afiected by varying temperatures or climates so that an ink of a fixed or standard character is applicable for universal use.

Having thus described some of the embodiments of my invention, what I claim and desire to secure by Letters Patent is,

1 A non-evaporating printing ink, consist ng solely of mineral oil, asphaltum, and a pigment.

2. A non-skin forming printing ink, comprising a cold dissolved mineral oil, asphaltum, and pigment base.

3. A non-evaporating printing ink, comprising mineral oil, asphaltum, and a pigment base cold dissolved and free from drying agents.

4. non-evaporating printing ink, comprising mineral oil, asphaltum, and anilin dissolved and commingled without the application of heat.

5. A non-evaporating printing ink, comprisin mineral oil, asphaltum, and a pigment ase commingled and dissolved substantially as described and in about the proportions stated.

6. A non-skin forming printing ink, comprising a mineral oil, ssyrian asphaltum, and a pigment base cold dissolved and commingled in substantially the proportions stated.

7. The process of making non-evaporating printing ink, consisting in cold dissolving v a mineral oil, asphaltum, and a pigment base.

8. The process of making printing ink, consisting in (1) dissolving a mineral oil and Assyrian asphaltum, and (2) adding a pigment base ground in mineral oil Without the application of heat.

9. The process of making n0n-evaporat ing printing ink, consisting in cold dissolving by agitation mineral oil, asphaltum, and coloring matter in substantially the proportions stated.

10. The process of making non-evaporating printing ink, consisting in cold dissolving by agitation in a mineral oil, asphaltum, and a coloring agent in substantially the manner and proportions stated.

11. The process of making non-skin forming ink, consisting in thoroughly dissolving and commingling Without vaporization or heating agents mmeral oil, asphaltum and a coloring agent.

In testimony whereof I have aflixed my signature in the presence of two Witnesses.
